The diagram, not drawn to scale, shows the distances between 4 cities.
- Yen travels from City E to City F and then to City H. Find the distance she has travelled in metres.
- The cost of petrol consumption for every km travelled is 50 cents. Find the cost of the petrol consumption to travel from City F to City G.
- Find the shortest distance to travel from City E to City H. Leave your answer in km and m.
(a)
Distance that Yen has travelled
= 12.4 + 11.6
= 24 km
1 km = 1000 m
24 km = 24000 m
(b)
Cost of petrol consumption to travel from City F to City G
= 2.16 x 0.50
= $1.08
(c)
Distance to travel from City E to City H via City F
= 13.9 + 9.3
= 23.2 km (Shorter distance)
Distance to travel from City E to City H via City G
= 12.4 + 11.6
= 24 km (Longer distance)
Shortest distance to travel from City E to City H = 23 km 200 m
Answer(s): (a) 24000 m; (b) $1.08; (c) 23 km 200 m
